Standard values for Rv or 2 x Rv:

 

 

V s

R v

2 x R v

12 V ±2 V

330 ohms

680 ohms

24 V ±2 V

680 ohms

1200 ohms

48 V ±4 V

3300 ohms

6800 ohms

In order to preserve symmetry, use 2 x Rv resistors with a maximum toler- ance of 0.5% only.

If the amplifier inputs are single-ended (grounded) or have no input trans- formers, wire either capacitors or optional transformers into the audio lines to prevent any current leakage into the input stage.

Cleaning

To clean the metal surfaces, use methylated spirits or alcohol. We recom- mend to wash the windscreen in a mild detergent solution. As soon as it is dry, the windscreen will be ready for use again.
